Well first let me say welcome to the boards. I know I'm pretty new here myself but I can tell you that we do have a wide aray of medical professionals here. As someone that has recently completed the EMT-B course I can offer these small tips of advice.
-Be prepared for class. Bring your books, paper for notes, and 2 pens or pencils. You would be amazed how many people fail at this very basic concept.
-Be attentive to the instructor and listen to what he or she has to say.
-Attend each class slightly early. You'd be amazed how much fun you can have and even learn from the instructor or other class mates BEFORE the class starts.
-Be ready to work as a team. In most services you will be part of a crew so be prepared to work as one. Learn your strengths and weaknesses.
-Dont be afraid to ask for help or clarification. Sometimes an instructor will throw around medical terms so fast your head can spin. Throw up that hand and ask "huh? what was that term?"
-Study groups. Preferably with people that are either in your class or have taken the EMT-B. Even better if they have acsess to equipment. (I.e Longboard, KED, AED, O2, Stretcher.)
-Youtube. Search for NREMT Practical Stations. Theres a group out of PA that did a great job documenting how your practicals are going to go.
-Have fun. Take it seriously but have fun. EMT's are a rare species. We deal with alot. If someone has called for you its usally one of the worst days of thier lives. So take that into consideration if someone is harsh or yelling at you. Be calming and soothing and not bossy.
-Show confidence. Take control but show compassion for your patients. (Esp the Psych ones
-And lastly, Never stop learning. Read this fourm, Read JEMS.com, Never stop learning. Theres always gunna be some new gadget or toy out there that might make your job easier.
I know its alot but if you put the dedication into it you will do fine. I'm here on this fourm if you need help too. Just drop me a PM if you got any other questions.
Good Luck and Have fun!
